Caz Graham visits the island of Anglesey, just off the north coast of Wales, where oysters are farmed in the waters of the Menai Strait. The strong currents which ebb and flow around the sandbanks bring a steady supply of food for the shellfish. Caz finds out how they are grown and cultivated, and learns about the effect that rising water temperatures are having. She meets the farm's owners, who have also made the most of their location, with its views of Snowdonia National Park, to set up a camping and caravan site.
